Verified step by step guidance1
Understand the definition of interstitial fluid: It is the fluid that surrounds and fills the spaces between cells in tissues.
Differentiate interstitial fluid from other body fluids: It is not the same as blood, which circulates within blood vessels, or intracellular fluid, which is inside cells.
Recognize that interstitial fluid is part of the extracellular fluid, which also includes plasma, the liquid component of blood.
Consider the options given: Interstitial fluid is not blood, not confined to specific organs, and not fluid released from the body.
Conclude that the correct description of interstitial fluid is 'the fluid that fills the spaces between cells,' as it matches the definition and characteristics of interstitial fluid.
